Windows Central Question

In the week or two I have updated to Windows 10 from 8.1. The surface Pro 3 has been automatically doing updates. 2 days ago the type cover stopped working and disappeared from devices. Today the wifi does not work and says "The Marvell AVISTAR Wire4less-AC Network Controller is not fixed. Experiencing driver or hardware related problems." Also in device manager "The network adapter is experiencing problems. Failed". The Bluetooth has also disappeared. Can you offer some advice on how to resolve this please. Also when I can get wifi and can restore my devices, should I go back to windows 8.1? Thanks.

go to device manager and disable the wifi and bluetooth adaptors and then enable them and see if that helps

Check this article for more info: https://www.microsoft.com/surface/en-us/support/networking-and-connectivity/cant-connect-to-a-wireless-network?os=windows-10

You can go back to windows 8.1 only if you do it before a month is over since you upgraded
